VALVE.

SPECIFICATION forming part of Letters Patent N0. 752,608, dated February 16, 1904.

Application filed September 10, 1903. Serial No. 172,611. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOSEPH UTRILLA, a citizen of Cuba, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Valve, of which the following is a full, clear, and exact description.

This invention relates to improvements in two-way valves, particularly for use in controlling the motive agent for hydraulic or similar-elevators, although it may be used under other conditions.

An object of the invention is to provide a valve of simple construction that may be readily and quickly operated.

I will describe a valve embodying my invention and then point out the novel features in the appended claim.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a section on the line 1 1 of Fig. 2 of a valve embodying my invention. Fig. 2 is a plan view thereof. Fig. 3 is a section on the line 3 3 of Fig. 1; and Figs. 4, 5, and 6 are sectional views on the lined 4: of Fig. 1, showing the diiferent positions of the valve.

Referring to the drawings, 5 designates the valve-casing, in which the valve 6 has rotary motion. opening 7 for the outlet of the motive agent discharged through a port 8, formed ina wall of the valve. Extended transversely in a straight line in the valve from side to side is a tubular port 9, designed to communicate with an inlet 10 and an outlet 11. The tubular port is substantially oval and has its greatest width transverse to the valves axis, so that a large port is provided in a comparatively small space. As here shown, the valve rests upon a wear-ring 12, which may be adjusted by means of screws 13. The bottom wall of the valve-casing 5 has an outlet 14,

At its lower end the valve 6 has an.

and extended upward from the valve and through a stuffing-box 15 on the top wall of the casing is the valve-stem 16, having a segmental pinion 17 on its end engaging with a segmental gear 18 on a shaft 19, supported in bearings 20, attached to the valve-casing. On this shaft 19 is a cord or cable wheel 24, attached to which is a counterweight 21 for antomatically moving the valve to closed position, as will be hereinafter described.

In the operation when the valve is in the position indicated in Fig. 4 pressure is ad mitted to move the elevator upward. When the solid wall 23, between the ports 8 and 9, is in the position indicated in Fig. 5, the pressure will be cut off and the elevator stopped. To cause the downward movement ofthe'elevator, the port 8 is to be moved into communication with the outlet 11, thus permitting the water or other motive agent to pass down from the pipe connecting with the outlet 11 and thence through the port 8 and out through the port or outlet 14. It will be noted that the whole movement of the valve is in the space of ninety degrees. Therefore it may be quickly operated in both directions.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- A two-way valve comprising a casing having opposite ports in its walls and an outlet in its bottom wall, a valve mounted to rotate in the casing and consisting of a hollow cylindrical shell, closed at the top and open at the bottom, and having a port through its outer wall, and a port formed by transverse walls distinct from but connecting with the outer wall of the shell.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.-

JOSEPH UTRILLA.
